摘　　要：目前由于下游建筑行业走势出现断崖式式下滑,钢铁行业生产形势日趋严峻,棒材行业首当其冲,品种规格单一,折旧高等因素造成的产品竞争力逐渐降低。为了充分提升产线竞争力,必须突破原有设计范围,开展有竞争力的高强钢系列品种的生产。另外由于行业内卷严重,很多产线都采取提速增产的方式来摊薄成本,相对于常规棒材轧制,短应力轧机减速机的负荷增幅很大,造成短应力轧机减速机故障频率增加明显。针对某钢厂成品轧机减速机轴承故障,结合轴承厂家提供标准与制造厂家提供标准进行比较,给出轴承故障的原因分析以及调整策略。At present,due to the trend of the downstream construction industry,the production situation of the steel industry is becoming increasingly severe,the bar industry is bearing the brunt,the variety specifications are single,and the high depreciation factors will inevitably cause the product competitiveness to gradually reduce.In order to fully enhance the competitiveness of the production line,it is necessary to break through the original design range and carry out the production of competitive high-strength steel series varieties.In addition,due to the serious coil in the industry,many production lines adopt the way of increasing speed and increasing production to dilute the cost.Compared with conventional bar rolling,the load of short-stress mill reducer increases greatly,resulting in a significant increase in the failure frequency of short-stress mill reducer.Aiming at the bearing failure of a finished mill reducer in a steel mill,this paper compares the standard provided by the bearing manufacturer with the standard provided by the manufacturer,and gives the cause analysis and adjustment strategy of the bearing failure.
